The rule of thumb is 15m (or 50ft) before you start to loose line rate. The best way to go is a DB-9 to RJ45 adapter. Use a straight ethernet cable and do all the pinouts on the adapter (http://www.commdevices.com/pdf/null-modem-rj45-db9-pinout.pdf) -- =Wayne On Mon, May 18, 2009 at 9:37 PM, Lee Sharp <[email protected]> wrote: > David Burgess wrote: >> >> If I understood you you're saying I should just construct a really >> long null modem cable using cat5.
